STRAINER.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed $eptember 22. 1906. Serial No. 335.793.

To all whom it may concern:

Be it known that I, ALBERT F. E'r'rnn, a citizen of the United States ofAmerica, residing at Ettersburg, in the county of Humboldt and State ofCalifornia, have invented new and useful Improvements in Strainers, ofwhich the following is a specification.

This invention relates to improvements in strainers and filters designedfor use in connection with water or other liquid conducting pipes, theobject of the invention being'to provide a device of this characterwhich is simple of construction, efficient in use, inexpensive ofproduction, and adapted to be readily applied to and removed forcleansing and repairs.

In the accompanying drawing,Figure 1 is a longitudinal section through aconducting pipe having the.

improved strainer arranged therein. Fig. 2 is a cross section on theline 22 of Fig. 1. Fig. 3 is a perspective view of the strainer per se.Fig. 4 is a part sectional and part side elevational view of a modifiedform thereof. Fig. 5 is a longitudinal section of a further modifiedform. Fig. 6 is an end elevation thereof. Fig. 7 is a longitudinalsection of the device as embodied in a filter.

Referring to the drawings, 1 designates a conducting pipe carrying atits outer end a faucet or valved discharge nozzle 2, said nozzle beingprovided with a coupling 3 internally threaded to receive the proximatethreaded end of the pipe andprovidcd at the inner end of this threadedportion with a shoulder 4 against which the end of the pipe normallybears.

The strainer is applied for use in the pipe in the manner illustrated inFig. 1, and comprises a foraminous tube 5, composed of wire of suitablemesh, perforated sheet metal or other suitable material, said tube beingof a desired length to effectually subserve the purpose and of lessdiameter than the pipe to form an intervening annular passage around thetube through which the water or other liquid circulating in the pipeflows thereinto. to ahead or disk 6 and at its rear end to a head ordisk 7. The disk 6 is circular in form and is clamped between theshoulder 4 and threaded end of the pipe and closes communication betweenthe pipe and faucet or nozzle except through the perforated strainertube, the said disk being provided with an aperture 8 communicating withthe forward end of the tube and serving as an outlet passage for theflow of the liquid from the tube to the' faucet or nozzle. The disk 7supports the rear end of the strainer tube within the pipeconcentrically with relation to the latter, and, as shown in the presentinstance, is of triangular form to space it from the pipe to provideports or passages for the flow of the liquid past the same and into thespace about the strainer tube. The said disk may, however, be of anyother form to subserve this purpose.

It will be understood that as the rear end of the The tube is secured atits forward end strainer tube 5 is closed by the head or disk '7, thewater will flow through the above mentioned ports past said disk andinto the strainer tube through the meshes thereof, which are closeenough to prevent the entrance of any foreign particles, the strainedliquid flowing from the tube through the outlet passage 8 into thenozzle. Hence the fluid will be thoroughly strained and purified in itspassage. The construction of the strainer and mode of mounting it shownand described enables it to be conveniently applied and removed in anobvious manner.

In the embodiment of the invention shown in Fig. 4, the head 7 isprovided with a sleeve 7 to inclose the adjacent end of the strainer 2.This sleeve slid-ably engages one of the ends of a sleeve or tube 8 offelt or other suitable porous textile fabric, which surrounds thestrainer tube 5 and is arranged between the heads 6 and 7, the sleeve ofthe latter serving to embrace and hold said sleeve 8 from longitudinalmovement. Upon removing the head 7, the sleeve 8 may be withdrawn in anobvious manner. The water filters from the pipe through the tube orsleeve 8 into tube or sleeve 5 and then discharges in the manner abovedescribed, this construction insuring a more perfect filtering of thewater.

In Fig. 5, the head 7 corresponding to head 7 in Figs. 1 to 4 inclusive,is provided with an inwardly projecting flange 7 fitting within the pipe1, and the strainer tube 5 is provided with a sleeve or covering 8 offiltering material, such as before described with reference to Fig. 4.The heads 6 and 7 in this (mbodiment of the invention are reverselyarranged with respect to the structure disclosed in Fig. l, the head 6being at the inlet end of the strainer in the direction of flow of thewater. The water here enters the tube 5 through the opening in thestrainer 6, thence flows through the tubes 5 and 8, and into the annularspace between the same and the pipe 1, and finally discharges throughthe h cad 7 at the out] ct end of the pipe, which is th read edfor thereception of the faucet 2. The head 7, in addition to being providedwith the sleeve 7 is formed with outlets 7 for the discharge of thewater and with a projection 7 to enter and support the contiguous end ofthe strainer tube. In this and the construction shown in Fig. 4, thesleeve 8 may be in the form of a tube adapted to he slipped endwiseon tothe tube 5, or it may consist of a wrapping about the latter-named tube.

It will be seen that the invention as thus far dcscribcd provides areversible strainer, in which the water may enter through one of theheads and flow through the tube, orfirst pass into the tube and thendischarge through the perforated head.

In Fig. 7, I have shown my invention as embodied in a filter adapted forattachment to the threaded nozzle of a faucet for filteringorstrainingthe water discharging therefrom. In this construction, the conductor 1is n the form of a casing having at its upper end a threador the tubeand between the same and a or casmg m ed inlet 9 for connection with thefaucet, and provided at its lower end with a discharge nozzle 10,threaded or otherwise detachably secured thereto. At its tipperend, thecasing is provided with a supporting head or tube 11 in opencommunication with the inlet 9 and threaded for the reception of theupper end oi the strainer tube 5, which is here in the form oi aioraniinous cylinder. This tube or cylinder rests at its lower end upona head 12 clamped by the nozzle 10 against the lower end of the casing land provided with discharge ports 13. The water from the nozzle entersthe filter through the inlet 9, thence flows into the tube 5 and throughthe latter and filtering sleeve 8 into the annular space between thesame and casing, and finally discharges through the ports 13 and nozzle10, as will be readily understood.

it ill be apparent, oi course, that this construction oi strainer orfilter may be employed in the line oi a fluid conducting pipe to filterthe fluid on its passage, and it will be obvious that by simplyreversing the parts, that is, respectively in aking the elements 10 and9 the inlet and outlet, the water may first be caused to enter thecasing, then pass through and into the filtering tube, and finallydischarge through the member 9.

Having thus described the invention, \\'ll ti-is('i21llil(?(l as new, i
